Haplocladium microphyllum reported for California is based on a collection obtained from near Los Angeles on Santa Catalina Island [see Koch 1950a; Sayre 1940]. We were not able to locate this specimen to validate this entry. The nearest herbarium specimen that were were able to find of Haplocladium microphyllum occurs in Arizona. We therefore have excluded this taxon until it can be confirmed for California.
